An object of this inventionis a shield of the character shownin the patent, to Otto Schwartz, No.1,519,011, granted December 9, 1924, the present shield having a sweepsheetiwhi'ch is provided on'its under surface. with a filter mediumdesigned to trapa large portion of the'dust which passes from'beto hindthe radiator and out from under the sweep sheetglt is intended tosodispose the filtering medium, whiclimay be steel wool saturated withan'odorless oily substance,

I that isremovable as a unit from the sweep -15 sheet. In thismanner-,replacement of the filtering medium, when it becomes cloggedwith dust-,may be readilyefiected. I

A further object isa' novel form of or connectio'n betweenthe'horizontal sweep sheet and the vertical back plate, so thatreplacement of the filtering medium may be effected without difficulty-A still further objectis a radiator shield wherein a dust proof joint orconnection be 7 tween the verticalback plate anidthehorizontal sweepsheet is provided andwherein a filtering medium is disposed in thepath'of the circulating air.

following description and the accompany ing drawings in which Fig. 1shows in outline a radiator provided with the shield of the noveldesign.

Fig. 2 is an enlarged detail sectional view of a portion of the sweepsheet.

Fig. 3 is asimilar view of aportion of they back plate and sweepsh'eetillustrating the joint or connection between them: a portion of thesweep sheet as if looking'upwardly towards the portion shown in Fig. 2.

Referring to the drawings, itwill be seen that there is providedon thefloor 10 and ad-' 4 jacent the vertical wall 12 a radiator 14 which maybe of anylconventional design. Disposed in back of the. radiator andleading from a point close to the floor to'a point above the top of theradiator is'a back plate 16 to which is detachably connectedtlie jointStill further objects will, readily occur to those skilled in the artupon reference to the sweep sheet 18 ofthe invention. -End flanges shownin dotted lines at'20 are 'connected to the back plate, and secured tothese end flanges: are mounting or fastening means ofi thev character:disclosediin the patent above mentioned,-although it will be understoodthatother mo ting means may be used ifdesired;

The-joint or connectionbeti'veen the back'-. plate 16 andthe sweep sheet18 is illustrated: best in Fig. 3 .and is. formedas follows The edge ofthe back plate 1.6 i's bent-in the form ofa reversed Stoprovide a grooveor pocket" 24; inwhich maybe slid aniedgeof the sweep sheet. 18.The-pocket '24. is made of such a sizeas t'oireceive theedge ofthe sweepsheet rathersclofsely so thatiasubstantially closev fit between themisprovidedythus preventing. the; gatheringiof dust inthe connectionl Itwill be observedthatzthe connection is substantially 1 air-tight; anddust-proofand being. so constructed forms an important partof thepresent invention. v Secured to "the under surface of the sweep sheet asillustrated in Figs. 2 and 4, are a plu-i rality ofzclips 30whichsecurea plateBfZ to the bottomof'thesheet." I The plate32 is inbenton three of itsedges to provide grooves: 34 to receive the outwardlybent'flang'es 36 of fthe wire cage '38,.a's' illustrated in.;Fig.-.2.Oneedge, preferably Further, the member 32 itself. is detachablefrOmEthesWeepsheet. sinceit can be slid out from between the clips andthe bottom of the sheet. I v

Disposed within the wire cage 38 is amass of mineral wool ,40 saturatedwith an odorless oilysubstance rendering the steel Wool} dust-collectingin its nature. The forward edgeof the sweep sheet is bent in the form ofa Jas illustrated at 42 to provide a pocket in which dust maybecollected.

Disposed above the horizontal sweep sheet is a cover -16 and between thelatter and the top surface of the sheet is a layer of heat insulatingmaterial such as asbestos at 48.

It will be observed that air which circulates around and thru theradiator in the direction of the arrows and which carries with it aconsiderable quantity of dust gathered from the floor and walls, isconducted 5 thru and against the mass of steel wool 40. A certainproportion of the dust carried by the air is collected on the wool,there to remain until the wool is replaced by a fresh quantity. Some ofthe dust that is not collected by the wool gathers in the pocket 42 ofthe sweep sheet, aswill be understood clearly, from where it can berem0ved.

It will also be seen that there has been provided a radiator shieldwhich traps aconsiderable quantity ofthe circulating dust altlmugh notinterfering appreciably with thleceircuhtion of air around the radiator.

Further, it will be seen that the dust coldevices are readilyreplaceable by Q fresh ones so that the, maintenance of the V efieieneyof the device will be a comparative- 1y simple matter. Y M

Now having described the invention and the preferred embodiment thereof,it is to be I understood that thesaid invention is to be limited, not tothe specific details herein set forth, but only by the scope of theclaim which follows. l

Whatlclaim is: a v Q In a radiator shield, at back wall, and a sweepsheet detachably connected thereto by mans of a substantially air-tightjoint, said sweep sheet comprising a horizontal plate having filteringmaterial on its under sur- 36 face, and a vertical J-shaped flangeproject ing downwardly and inwardly from the front edge of the sweepsheet to serve as an auxiliary dust trap, the joint between the backandthe sweep sheet including a pocket- 40" forming bend on the backsheet into which an edge of the sweep sheet is adapted to fit, thefiltering material being disposed in a M wire cage removably supportedon the under surface of. the sweep sheet, the mateil rial beingremovable from the cage so as to be replaced if desired theshield havinga removable cover fitted'over the sweep sheet and the upper edge of theback plate, an concealing the J shaped flangeof the sweep shat. a
